ENGINE MAINTENANCE
Engine Lubrication
Proper engine lubrication depends on ambient temperature
and where the vehicle will be operated. Use the recom-
mended oil for the weather conditions outside.
NOTE: Engine lubricating oil change intervals are
not listed here. For specific engine maintenance
procedures, oil change intervals, filters, and other
recommendations, refer to the engine manufac-
turer’s Service Manual or the Engine Operation and
Maintenance Manual.
Service Intervals
• Check engine oil daily.
Oil Draining:
• Refer to the engine manufacturer's
Engine Operation
and Maintenance Manual
supplied with your vehicle for
information about draining and refilling engine oil, engine
crankcase capacity, engine oil type, and changing oil fil-
ters, etc.
WARNING! Hot engine oil can be dangerous. You
could be seriously burned. Let the engine oil
cool down before changing it.
• Drain the oil into a container designed for this purpose.
• When draining the oil, remove the plug with the proper
size wrench and keep as far away as possible. Always
keep your forearm parallel to the ground to help prevent
hot oil from running down your arm.
• The oil filler cap must be secured to avoid oil spill caus-
ing a potential fire hazard.
Oil Level Check
• To check the engine oil level, park the vehicle on level
ground and wait 5 minutes after shutting the engine OFF.
This allows time for the oil to drain to the oil pan.
• Remove the dipstick and wipe it off with a clean, lint-free
rag.
